I RAILFASTENING DEYIGE.

Application filed November 14, 1924. Serial No. 749,930.

To all whom it may concern:

Be it known that I, SAMUEL B. KULL, a citizen of the United States, and a resident of Roslyn, in the county of Nassau and State of New York, have invented a new and Improved Rail-Fastening Device, of which the following is a full, clear, and exact description.

This invention relates to a rail fasteningv device. An object of the invention is to provide a device which is simple and efficient and which makes it practically impossible for a spike to be removed from a tie and contact with a rail after it has been once put in. place except by the use .of such instruments as claw bars.

Another object concerns the simple and efiicient combination between a spike, a rail and a rail plate whereby when the spike is driven into a tie and in contact with the rail it automatically locks to the rail plate.

A further object concernsthe prov1s1on of simple and efficient means whereby the spike is provided with means, preferably formed integral therewith, which will automaticallylock with the rail plate or bed plate as the spike is driven into the plates.

The invention is illustrated in the drawings, of which Figure 1 is a sectional view through a rail, the bed plate, the tie and the spike, showing the parts in their operative position;

Fig. 2 is a plan view of the rail plate;

Fig. 3 is an enlarged section showing the spike about'to be introduced into operative relation with the rail plate; and

Fig. 4; shows a similar section in which the spike is in full operative position.

The form of the invention shown in the drawings is av preferred form, although it is understood that modificationsin the construction and arrangement of the parts and in the character of the materials used may he adopted without departing from the spirit of the invention as set forth in the appended claims.

The invention in general concerns a spike which is provided with a pro ecting pin which is preferably formed integral therewith. As the spike is driven into the tie through the rail plate adjacent the rail, the pin enters an auxiliary hole in the plate and by reason of the slope of the walls of the hole is bent so that it underlies a portion of the plate when the spike is driven fully into position. This interlocking action of the pin with the rail plate prevents the spike from being withdrawn from contact with the rail except by the use of special instruments.

In other words,'the spike is provided with means which, as the spike is driven into re lation with the rail, interlocks with the rail plate to hold the spike thereto.

In the preferred form of the invention shown in the drawings is illustrated the devlce as applied in association with a tie 1, a rail plate 2 and a rail 3. The rail plate is provided with the usual flange 4 against which one edge of the rail is adapted to lie. The plate is also provided with apertures 5 through which the main bodies of the spikes are adapted to project. Adjacent each of these spike apertures is located an auxiliary aperture 6. The axis of each of these apertures 6 is disposed at a considerable angle to the axes of the spike apertures 5. The

spike is preferably provided with a pin or projection 7 disposed adjacent the head 8' of the spike and preferably made integral therewith. This pin is disposed, preferably, at the rear of the spike near the top and as the spike is driven through the spike aper ture the end of the pin 7 enters the aperture 6, and as the spike is driven down this pin is bent to conform to the axis of the aperture 6 so-that when the spike is driven in, as shown in Fig. 4, the pin has been deflected to project substantially into the aperture 6, and by reason of this projection the pin and the rail plates are interlocked so that any tendency of the spike to creep out of its aperture is prevented by the locking engagement between the pin 7 and the aperture 6 because of the'fact that the upper surface of the pin lying in the aperture 6 will abut the walls of this aperture to prevent such a movement. The only way in which the spike can be taken out of the rail plate is to, usea claw bar of sulficient power to forcefully lift the spike out of the aperture and in so doing bend the pin. It is apparent, however, that the spike can be driven into ,the tie direct without passing through the through the rail plate and a pin formed integrally on the spike near the head adapted to engage With the rail plate as the spike is driven therethrough to prevent the 'removal of the spike therefrom.

2. In combination, a rail plate having a. spike aperture and an auxiliary aperture adjacent said spike aperture, the axes of said apertures being inclined with respect to each other, a spike to be driven through the spike aperture, and a pin formed integrally 0n the spike adapted to enter the auxiliary aperture as the spike is driven in place said pin having an initial inclination different from the inclination of the auXiliary aperture and adapted to be bent from its normal inclination into alignment With the inclination of the auxiliary aperture as the spike is driven in place, whereby the pin as it lies in the auxiliary aperture Will be interlocked With the plate to prevent the removal of the spike from the rail plate.

3. In combination, a tie plate having an inclined hole therein adjacent the point Where a spike is to be driven into the tie a spike having an integral pin near its head which is adapted to enter said hole as the spike is driven into the tie to lock the spike to the tie.
